Here’s some pictures from my layout, and some of the electronics that I’ve been working on for the switches.

I’ve been working on using a Raspberry Pi with a previous build originally for my Arduino that uses two 8 bit shift registers to talk to 16 relays. I’m also working with an MCP23017 port expander to be able to wire up 16 buttons to control them locally, for manual operation of the switches. I’ll probably be using more to get some LED status lights on the control board, but that’s still in the air.
